Variable: math-tzone-names

math-tzone-names is a variable defined in calc-forms.el.gz.

This variable is obsolete since 32.1; new software should use numeric abbreviations like "-0500" instead of relying on this variable's contents.

Documentation

List of lists describing the different time zone names.

For example, the sublists for circa-1970 time in New York look like this:

 ("EST" 5 0) ; Abbreviation, then standard adjustment,
 ("EDT" 5 -1) ; then daylight saving adjustment.
 ("EGT" 5 "EST" "EDT")) ; Generalized time zone.

This variable's default value contains abbreviations like "PST" that have their circa 1970 meanings even if timekeeping has changed since then.

Probably introduced at or before Emacs version 32.1.
